Optimizing CPQ Applications

September 9, 2019

User experience covers a variety of topics. A poorly designed user flow or a badly designed screen layout is irritating, but nothing gets users more frustrated than application latency. On initial launch, a CPQ application can have really good performance, but over time it degrades: application optimization is not a single task, it’s more like a maintenance contract! CPQ applications spawn data, valuable data and simply archiving that overhead is not ideal.

At channelcentral we used to speak about a four second rule. It’s an arbitrary number, but we believed that if a user didn’t see a result on click within four seconds they’d click again as the assumption is they didn’t click correctly OR the application needs a reminder. Today: four seconds needs to be nearer one second – user expectations are higher due in part to the Smartphone experience.

channelcentral recently undertook an architectural review of the applications that run in its “CMS” framework. One finding was that a lot of latency was caused by “Web Services” where applications pull in data to enrich the content with time sensitive data (notably price and inventory). Users were experiencing wait times of between four and 10 seconds and that was clearly unacceptable.

The Development Team looked at Microservices (MSA: Micro Service Architecture) as a potential solution to latency caused by data requests. Once deployed, application performance improved by up to 10X.

Moving from monolithic to modular has other benefits in terms of deployment, fault detection and code maintenance. There are some ‘cons’ with Microservices, but improving performance to that extent makes it an architecture we’re investing in.
